. SPECIFICATION formingspart of Letters Patent 'No. 760,859, dated May24, .1904. r L

" a lican fiid'iei z'aleos. ;Seria1Nn.159,166. oam qe To all whom it mayconcern Be it, known that I, WILLIAM H. ELLIS, a citizen ofthe UnitedStates, residing at Boston, in the county, of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Pile-DrivingDevices, of which the following is a specification.

This invention relates to improvements in pile-drivers, and has for itsobject to provide a pile-driving construction by means of which pllescan be driven underwater as well as on land, the hammer eflicientlyguided to fall in alinement with the pile, and piles of any ,requiredlength driven to any 'desiredfpoint above or below -the surface ofthewater.

In carrying out this invention Ifem'ploy with a pile-driver anadjustable hammer guide or chute,"which isjsubstituted for the.ordinaryfguideway between the uprights in a .pile d'river, up and downwhich the hammer slides. The adjustable hammer guide and chute is placedin any desirable position between said uprights of the pile-driver andas the pile is driven is lowered till, the vdesired position is attainedfor the depth at which the pile is to be driven., '1"

Referring to the accompanying drawings, in which similar figuresOfreference indicate like parts, Figure 1 is a view in elevation of apile-driver, showing the invention. Fig. 2 is a view in elevation,showing the hammer guide or chute. Fig. 3 is a transverse sectionthereof, on the line on m, Fig. 2. Fig. tis a detail view showing theconstruction of the hammer guide or chute. Fig. 5 is a detail viewshowing a modification of the hammer guide or chute.

In carrying out my invention I employ a pile-driver 1 of the usual formof construction, but omitting the slideways or guides for the hammerfrom the uprights 2, In connection with this pile-driver 1 I provide ahammer guide or chute 3, of any suitable con struction, and adapted tobe located in adjustable position between the uprights 2.. The hammerguide or vchute is preferably con-. structed as follows: It is made upin sections 4:, of any suitable length, fastened together. Each sectionas, here shown consists of four angle-irons 5, arranged at the cornersof a square, and, held in this position byfbeing secured by rivets 6 totransverse flanged plates 7. The angle-irons 5 are braced by means ofcrossed metallic strips 8, secured together and to the angle-i rons .5by rivets 6. The sections 4 are fastened together by bolts and nuts 9,en-,

gaging the flanges 10 of the plates 7. As many of the sections 4 areemployed asare necessary to form a chute of the required length.

'In the foregoing construction the angle-irons '5 of the sections 4,abutting end to end, form the slideways or guides for the hammer. Ashere shown Ia hammer 11 of square shape is employed, which is adapted toslide be tweentheangle-irons5 and is provided with an'extendedportion12,.whichis secured at its end to a wire rope 13, passing over a pulley14 to ahoisting-drum. (Notshown.) The hammer guide.: or chute is notnecessarily of a square shape, butmay' be formed'with two or moreslideways for the hammer, according to the shape of the latter, toadapt. it to the chute. ..The lower end of the chute 3 is secured bycross-bands15, riveted to the angleirons v5. In order to readilyintroduce the hammer into'the chute 3, its uppercnd is preferably formedwith an enlarged or flaringshaped top 16, constructedwith the inclinedstrips 17, fastened together at their upper ends by the riveted bands18.

In order to raise the chute 3 into position, it is provided at its upperend with suitable means for attaching it to a lifting mechanism and, ashere shown, with a pair of angle-irons 19, one on each side of the chute3 opposite to each other and riveted to the strips 17 and each having anear 20, with an eye 21, riveted to the angle-iron 19. By means of thisde- The pile-driver 1 being in position, the chute 3 is hoisted intoposition by means of the hoisting mechanism, hereinbefore described,between the uprights 2 and is secured in place by lashing or otherwell-known means. The pile to be driven is then raised by said hoistingmechanism and is lowered into the chute 3, the top of the pile beingbelow the enlarged top of the chute. The pile is then driven by thehammer, and as the pile is driven down the chute 3 may be lowered untilits lower end is adjacent to the bottom or substance into which the pileis driven, when the driving of the pile may be continued until thedesired position is reached. p

While the chute 3 has been shown and de scribed as being separable fromand independent of the uprights 2, it is not intended to limit theinvention to such construction and arrangement, as the invention broadlycontemplates a hammer guide and chute located and secured and adjustablein and removable from the uprights of a pile-driver in any suitablemanner.

In order to obviate the hoisting of the pile when it is inserted in thechute 3, the latter may have one side hinged, so as to be opened %ndintroduce the pile laterally, as shown in ig. 5. It will be seen thatthe chute constructed as herein set forth presents an open frameworkwhich is light, strong, durable, and economical.

By means of this device piles may be driven under water to aconsiderable deptl1, and the necessity of cutting ofi? the end of thepile, as in the old way, obviated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with a pile-driver, of a hammer guide, or chute,independent of the pile-driver, and laterally, and vertically, ad-

in said uprights, as herein set forth.

3. A hammer guide, or chute for piledrivers, independent of andlaterally, and vertically adjustably and removably connected with theuprights of the pile-driver, and consisting of an open framework, formedof guideways for the hammer, and braces, and connections, holding saidguideways together, as herein set forth.

4:. A hammer guide, or chute for piledrivers, consisting of a number ofsections bolted together, each section formed of guides for a hammer;cross-braces riveted to said guides, and flanged plates connecting theends of said guides together, and bolted to the adjacent flanged plates,as herein set forth.

5. A hammer guide, or chute for piledrivers, consisting of an extendedopen framework, having guides for the hammer, and an enlarged upper end,as herein set forth.

6. A hammer guide, or chute for piledrivers, independent of andlaterally, and vertically adj ustably and removably connected with theuprights of the pile-driver, and consisting of an extended openframework, with guides for the hammer, and means for attaching the chuteto a hoisting mechanism, as herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
